oleophilic
Definition
- Adjective:
- Having a strong affinity for oils rather than water: Describes a substance or material that is easily wetted by, attracts, or absorbs oils and other non-polar liquids, while typically repelling water.
Usage Examples
- Adjective:
- The oleophilic sponge quickly absorbed the cooking oil spill.
- Oleophilic materials are used in filters to separate oil from water.
- This fabric's oleophilic nature makes it unsuitable for raincoats.
Advanced Usage
- Scientific/Technical Context: The term is often used in chemistry, environmental science, and materials engineering to describe the preferential interaction with oils.
- The researchers developed an oleophilic membrane for more efficient oil-water separation.
Variants and Related Words
- Oleophobic (adj): Having a strong aversion to oils; repelling oils.
- An oleophobic coating on a smartphone screen helps prevent fingerprint smudges.
Synonyms
- Lipophilic: Having an affinity for fats and oils (often used in biochemical contexts).
- Hydrophobic: Repelling water (a common, correlated property of oleophilic materials).
Notes on Meaning
- The "affinity" described is a physical-chemical property, not a conscious preference. It is the opposite of oleophobic.
- While oleophilic substances attract oils, they are often simultaneously hydrophobic (water-repelling), as the two properties are frequently linked.
Adjective
-
